Consider item options for selection widget when no mapping is defined

[lolodomo]

As discussed in eclipse-archived/smarthome#4942 it would be cool to implement this feature in the Android app too.
I just implemented it in Basic UI and Classic UI; it was already present in Paper UI.

@lolodomo Is there a quick way to test this with the demo setup?

[mueller-ma]

There is an example sitemap in eclipse-archived/smarthome#4942 (comment). I recommend to check the rest api if the values are present. If not, you need to update your oh server.

[maniac103]

Yes, but AFAICT an item which is linked to a special channel with options support is needed. My question is whether there's a way to have such a channel without the need for special hardware support.

[lolodomo]

No I don't think this is available in the demo sitemap. It requires using a binding that defines some options for a channel, either statically or dynamically.
I used the netatmo binding for my tests.

[maniac103]

Which of the Netatmo channels does have options? I do have a Netatmo station, so that one would work well for testing for me.

[mueller-ma]

Your PR worked for me. Maybe @lolodomo can test it as well so you don't have to test it.

Temperature trend and pressure trend.

[maniac103]

I don't see any trend channels either for the indoor or the outdoor sensor ... I guess this is some post-2.3 thing? If so, I'd like to rely on @mueller-ma 's testing :-)

[lolodomo]

No this is old.
